HATPIN GUARD.

Specification of Letters Patent.

Patented Mar. 14, 1922.

Application filed November 22, 1921. Serial No. 516,919.

1 '0 all 20 item it may concern.

Be it known that I, Crmnnns ILisrnn, a citizen of the United States of America, and resident of Bridgeport, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Hatpin Guards, of which the following is a specification.

This invention relates to a hat-pin guard,

and it has for its primary object to provide a' simple, inexpensive and practical device whereby the pointed ends of hat pins are shielded and whereby such pins are effectually retained against chance withdrawal.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which Figure 1 is a side elevationof a hat pin equipped with myimproved guard;

Figure 2 is an enlarged longitudinal section of the guard;

Figures 3 and f are sections taken, respectively, on lines 33 and 4- 1, Fig. 2; and- Figures 5 and 6 are enlarged views of two different types of points for the shaft of the Referring to said drawings, 1 indicates the shaft of the pin which may either have a reduced neck 2 slightly rearward of its point, as shown in Figs. 2 and 6, or may have its point of approximately spear-head. form with its butt portion slightly exceeding in diameter that of the shaft, as shown at 8 in Fig. 5.

The guard forming the present invention comprises an approximately cylindrical body 4- of metal or other suitable material which constitutes a sheath for the pointed end of the pin, said sheath having an axial bore 5 of suitable length extending thereinto for the reception of said pin-point. EX- tending diametrically through said sheath is a rectangular orifice 6 in which is slidably disposed a sheet-metal. plate or tongue 7 which is attached at its outer end to a laterally directed terminal arm 8 formed upon an end member 9 of a coil spring 10. Said spring is disposed within the outer end of a channel-like recess 11 provided in a side of the sheath 4: and is carried by a transverse pin 12 which has its opposite ends mounted in said sheath at opposite sides of said recess. The opposite end member 13 of said spring 10 rests upon the bottom of said recess, extending inwardly along said bottom.

An aperture 14 is provided in the tongue 7 at a point which, in the normal elevated position of said tongue, is located above the level of the bore 5, said aperture being of a width or diameter approximating that of said bore and being adapted, when in register with said bore, to permit the pointed end of the pin to pass therethrough. Leading longitudinally downward from said aperture 14:15 a slot 15 having a width sufliciently great to receive therein, when the pin is of the form shown in Figs. 2 and 6, the reduced neck portion 2, but of insufficient width to permit retraction therethrough of the pointed end; or, when the pin has the enlarged pointed-end form shown in Fig. 5, the width of said slot is insufficient to permit retraction therethrough of the enlarged pointed end, The aperture 14 and slot 15 together form an opening or slot of keyhole form, hereinafter termed a keyhole-slot.

As is apparent from the foregoing, in order toeflect application or removal of the guard, the tongue 7 must be depressed against the tension of its supporting spring 10 to a point at which the aperture 14: is alined with the bore 5. Following application, the spring maintains the tongue elevated to a position in which the pin-shank is received in the lower end portion of the keyhole slot and in which, consequently, chance detachment of the sheath is effectually prevented.

To facilitate application of the guard, the inner end of the sheath has formed therein a conical recess 16 forming a guideway lead ing to the adjacent end of the bore 5, as shown.

What is clamed is 1. A hat-pin guard comprising, in combination with a hat-pin having a portion located rearward of its pointed end of relatively reduced diameter, a body member adapted for mounting in sheathing relation to said pointed end, said member having a longitudinal point-receiving bore therein and also having an orifice transversely crossing said bore, a tongue slidable in said orifice and having therein a keyhole slot through which said pointed end of the pin projects, and a spring normally maintaining said tongue in a position in which the reduced portion of the pin is received by the narrower portion of the slot, said tongue being depressible to position the larger end of the slot in aline- 'ment with the bore of said body member.

2. A hat-pin guard comprising, in combination with a hat-pin having a portion located rearward of its pointed end of relatively'reduced diameter, a body member adapted for mounting in sheathing relation to said pointed end, said member having a longitudinal point-receiving bore therein and also having an orifice transversely crossing said bore, a tongue slidable in said orifice and having therein a keyhole slot through which said pointed end of the pin projects, and a spring mounted on said body member, said spring having a portion receiving bore and an orifice crossing said bore, a tongue movable in said orifice and havinga longitudinal keyhole slot therein,

a spring yieldingly supporting said tongue and'normally maintaining it in a position wherein the reduced neck of the pin is re ceived by the narrower portion of said keyhole slot, said tongue being dep'ressible I against the tension o-f sa-id spring for positioning the wider portion of said slot in alinement with the core of the body member, saidmember having therein a recess in which said spring is mounted.

4. A hat-pin guard comprising, in combination with a hat-pin having a reduced necklocated rearward of its pointed end, a body member adapted for mounting in sheathing relation to said pointed end, said member having therein a longitudinal pointreceiving 'bore and an orifice crossing said bore, a tongue movable in saidorifice and having a longitudinal keyhole slot therein, said member also having a recess in a side thereof, a pin crossing said recess, a coil spring carried by said pin within said recess and] having a portion disposed in yieldingly supporting relation to said tongue whereby the latter is normally held in a position in'which the reduced neck of the hat-pin is received by the narrower portion of said keyhole slot, said tongue being depressible against the tension of said'spring to position the wider portion of said slot in. alinement with the member. a a
